BV03C 产品概述

BV03C 是 Bencent(槟城)推出的一款小尺寸双向瞬态电压抑制器(TVS),封装为 SOD-323,专为静电放电(ESD)和浪涌保护设计。该器件在小体积下提供可靠的浪涌吸收能力,适合对体积、响应速度和线缆辐射敏感的信号/接口保护场合。

一、主要参数与其含义

  • 极性:双向 —— 可对正向和负向冲击对称钳位,适用于双向信号线。
  • 反向截止电压 Vrwm:3 V —— 在此以下器件不导通,注意选择时应大于系统正常工作电压。
  • 钳位电压 Vc:5.15 V —— 在规定脉冲(8/20µs)下的最大钳位电压,表征保护电平。
  • 峰值脉冲电流 Ipp:1 A @ 8/20µs —— 能承受的瞬态峰值电流能力。
  • 峰值脉冲功率 Ppp:150 W @ 8/20µs —— 在 8/20µs 波形下的峰值吸收能力。
  • 击穿电压 Vbr:4 V —— 进入击穿区时的典型电压。
  • 反向电流 Ir:20 µA —— 在 Vrwm 下的漏电流大小。
  • 结电容 Cj:1.5 pF —— 对高速信号的负载小,适合对带宽敏感的信号线。
  • 工作温度:-55 ℃~+150 ℃;防护等级:符合 IEC 61000-4-2 标准(ESD 保护)。

二、产品特点

  • 小型封装(SOD-323),便于密集布板和自动贴装。
  • 双向结构,适合差分线或可能出现正负瞬变的接口。
  • 低结电容(1.5 pF),对高速数据线影响小,适合需保持信号完整性的场合。
  • 低漏电(20 µA)有利于低功耗系统。
  • 宽温度范围和符合 IEC 61000-4-2 要求,适应性强,可靠性高。

三、典型应用场景

  • 3.3 V 或更低电平的接口保护(如某些 UART、I/O 口、传感器线)。
  • 高速差分或单端信号线的 ESD 保护(在确认工作电压匹配的前提下)。
  • 工业通讯接口、仪表、便携式设备外部接口与连接器的浪涌/静电保护。
    (注意:若系统工作电压高于 Vrwm(3 V),需谨慎选型或考虑单向更高 Vrwm 的 TVS。)

四、PCB 设计与使用建议

  • 尽量靠近受保护的接口或连接器放置 TVS,走线短且宽,减少串联电感与阻抗。
  • 对于高速差分线,保持 TVS 两端到线对的对称布局,避免引入不对称干扰。
  • 如需进一步抑制峰值电流,可在信号线上配合小阻值串联电阻或熔断器使用,改善浪涌分流与热分散。
  • 注意焊接与回流工艺兼容性,SOD-323 兼容常见 SMT 工艺,贴装后检测焊点可靠性。

五、选型与可靠性注意事项

  • 核对系统工作电压与 Vrwm,Vrwm 应高于正常工作电压以避免常态漏电或误导通。
  • 关注钳位电压 Vc 是否满足被保护器件的耐压要求(5.15 V 在指定脉冲下),避免被保护器件因钳位电压过高受损。
  • 评估实际的脉冲能量需求,确认 Ppp/Ipp 能满足典型的浪涌/雷击情形。
  • 在严格的高压或汽车环境下,补充参考器件的资格认证和长期可靠性测试报告。

总结:BV03C(Bencent,SOD-323)以小封装、低电容和双向钳位为特点,适用于 3 V 级或以下信号线的 ESD/浪涌保护。在实际应用时,请依据系统电压、能量需求及信号完整性要求合理布局与配合外围元件,确保长期稳定工作。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
